The reflectivity of an optical surface can be reduced by the addition of one or more non-absorbing dielectric films. An anti-reflective coating will also enhance transmission in a series of optical components.
- A single layer (quarter wave) of MgF2 will typically reduce reflectivity (glass with a 1.52 index) from 4% to 1.5%
- A multi-layer AR design can reduce reflection from 4% to .3% in the visible
- A “V” design can reduce reflection to .1% across a narrow band of wavelength
- Anti Reflective coatings can be designed to function in specific bands such as UV, IR and NIR.
- Large Format (up to 35″ diameter)
- Low Cost (large volume throughput coaters coupled with low overhead operations)
- Tight Tolerance (±5nm at 50% transmission)
- Glass or plastic Substrates
- Volume Production ( fourteen 96″ diameter vacuum PVD chambers)
- Short Lead Times
